I have $35,000 cash, no debt, my wife and I have 720-740 credit scores, and we have approx. $85,000 household income.

We'd also pay off our ~$70k of student loan and credit card debt.

I currently have funding from my credit union and SBA loan

I'm sure there is a local credit union in Atlanta that has some decent rates with a first year locked in rate.

Use a credit card for all business expenses for air miles and easy tracking. 

credit card for business expenses only.

Thanks 1) the city of Chicago has terrible rules against landlords, as an example Doing this from memory, but I think landlords are required to pay interest on an annual basis to their tenants. 

This way you have immediately created separation and should something terrible occur and you be found liable / negligent, your primary residence and bank account are more so protected.If you purchase the property in your name, it’s a personal asset.

Without established credit, you will need a co-signer.
